Abstract :
Thales Alenia Space - Italy (TAS-I) Radio Communication Equipment Group has developed in the last few years a very competitive Digital Platform for Satellite Secure Communications which has been largely used in Telemetry, Tracking and Command (TTC) link for military-oriented programs. The standard Direct Sequence Spread Spectrum Anti-Jamming performances are further enhanced by an Adaptive Digital Filtering to remove part of the interference energy before codes correlation, allowing to cope with a Jammer over Signal Power ration (J/S) up to 50dB. Moreover, PN codes with several years period increases furthermore Data Confidentiality and Transmission Secrecy. This paper offers a complete overview of the advanced Spread Spectrum Equipment for Satellite Secure Communications.
